[j-nsp] IPv4 BFD flaps on MX204

[Mihai]

Hi,

I have a MX204 with a couple of OSPF/OSPFv3 adj to other MXs over two 
et- interfaces, BFD enabled for both protocols.
At random intervals the IPv4 BFD sessions are flapping with or without 
the 'no-delegate-processing' option, however the IPv6 sessions are 
stable (they are using the same timers).

Did anyone experienced something like this? The router is running 18.2R3-S3.


Thanks!
